4.6 How to use this product
4.6.1.3. Check that the battery cover is firmly closed.
4.6.1.2. Check whether there are foreign bodies under the anti-fall sensor to prevent abnormal anti-fall perception. (It is strictly
forbidden to be squeezed by external forces)
4.6.1 Pre-operation inspection
4.6.1.1. Check track surface cleanliness to prevent significant loss of grip. (It is forbidden to lift the upper hanging part of the track
to prevent deformation and damage of the front and rear axles)

4.6.1.5. Check whether the cleanliness of the camera lens and the body of the exposure box and the shading plate
completely cover the projection plane area of the exposure box to prevent sunlight and dust from interfering with the camera.
4.6.1.4. Check the cleanliness of the suction cup surface at the bottom of the central sucker assembly to prevent a significant reduction in grip.
4.6.1.6. Check the type of roller brush and whether it is deformed to prevent the cleaning effect. (Refer to "Description of Brush
Component Types" on page 3 for usage scenarios corresponding to brush types.) * When the roller brush is idle, Should be on the
motor, erect rely on placing, Avoid compression
deformation of roller brush bristles.
* If the bristles are deformed under pressure for
a long time,
It will cause the bristles to become irreversibly
deformed.
* When moving the roller brush, special handle
should be raised. It is strictly forbidden to pull the
roller brush shaft to prevent deformation and
damage of the roller brush shaft.

4.5.2 Placing
4.5 How to use this product
1. The number of turns is equal to the number of turns in a single row multiplied by the number of array rows.
3. Generally, use the side that is easy to carry and operate the device as the starting end, that is the bottom of the array.
Vertical layout(V)
Three turns in a row
2. Select the starting point with the least number of turns for H autonomous operation.
Horizontal layout(H)
Six turns in two rows
Turn times of V autonomous operation= 8 Turn times of H autonomous operation= 10
A row requires two turns
Crossing requires two turns
* Ensure that the surface of the initial position is clean to prevent the product from slipping or falling due to heavy contamination
of the tracks

4.6.3 Start the Kwun
1. Corner placement
Select the starting point with the least number of turns for
horizonal autonomous operation.
Kwun is placed on the bottom corner of the left and right
sides of the photovoltaic array that meets the requirements.
3. Position calibration
Adjust the horizontal central axis of the device to the spacing line of the
cells in row 2 and row 3 in the lower corner, and the horizontal central axis
to the spacing line of the cells in row 2 and row 3 in the lower corner.
2. Turn on the power
Press the power button to start the device. When the
first red light is often off (the buzzer rings once), the
device is normal and enters the initialization state.
4. Start the job
When the green light is always on and the red light is often off, the device
is normal and the initialization is successful, then press the Start/Standby
button to make the device start autonomous operation

After the start and identification is completed, the Kwun climbs up to the top of the photovoltaic array and tries the direction.
After the direction is determined, the operation begins. The Kwun turns around to span until the array is covered, and chooses
the termination according to the berthing mode.
